Merge with Ballast water discharge and the environment

The Ballast water discharge and the environment article does not present sufficient information to stand on its own and the section on this article about ballast water discharge is currently blank. Ballast water discharge and the environment should be merged here. Neelix (talk) 01:53, 24 March 2011 (UTC)

• Definitely support you on that one. That article is basically a thin amount of info spread to take up more room, and the merge you propose could certainly be performed without the loss of any significant content.--Yaksar (let's chat) 01:58, 24 March 2011 (UTC)

Merge with Ship pollution and Ballast water regulation in the United States

The encyclopedic difference between ship pollution and the environmental impact of shipping is small. For this reason, Ship pollution should be merged here. Since Ballast water discharge and the environment was recently merged here, I recommend that Ballast water regulation in the United States, a subarticle of that article, be merged here as well. Neelix (talk) 01:13, 30 March 2011 (UTC)

If you're proposing that, may I recommend also including Cruise ship pollution, which is just about ship pollution and not related to cruises?--Yaksar (let's chat) 01:15, 30 March 2011 (UTC)

Makes sense to me. Neelix (talk) 14:33, 30 March 2011 (UTC)

Reference National Research Council Study on the Regulation of Ballast Water

I'm suggesting adding the following information to the "United States" part of the "Regulation" section of the "Ballast Water" portion of the article.

To minimize the spread of invasive species in U.S. waterways, the Environmental Protection Agency and the U.S. Coast Guard are developing plans to regulate the concentration of living organisms discharged in the ballast water of ships. A June 2011 National Research Council study provided advice on the process of setting these limits. The study found that determining the exact number of organisms that could be expected to launch a new population is complex. It suggested an initial step of establishing a benchmark for the concentrations of organisms in ballast water below current levels, and then using models to analyze experimental and field-based data to help inform future decisions about ballast water discharge standards.

Please let me know what you think of this suggestion— Earlgrey101 (talk) 20:37, 21 June 2011 (UTC)

That looks good. Please add the author, title and publication date in your references. It would also be a good idea to add this paragraph, or something similar, at Regulation of ship pollution in the United States. Moreau1 (talk) 01:20, 22 June 2011 (UTC)

Thanks, OK I'll go ahead and add this. Earlgrey101 (talk) 19:49, 22 June 2011 (UTC)

Recommend to add a section on shipping and climate change

I recommend adding a section on the greenhouse gas emissions and how they or aren't addressed in international protocols and national climate change mitigation plans. Here is one place to start (see reference). The mentions in the article are brief and not up to date. Consolidating them, and expanding and updating on this topic would improve the article. Wish I had time to do so. Coastwise (talk) 00:37, 5 November 2011 (UTC)

Change Title to Green Shipping

Green shipping is the current trend in the shipping industry, though nowhere on the internet you can find a proper definition. The German version that is linked to this article is Umweltschutz in der Seeschifffahrt, that is "Environmental protection in maritime shipping". I suggest to change the title of this article to Green Shipping and to change the structure of it. In my opinion it should provide firstly a little definition of green shipping: "Green Shipping refers to the set of all actions aiming at reducing the environmental impact of shipping." Then explain what actually is the environmental impact of a ship (there are more categories than those in presented in this article) and how shipping companies and regulators are trying to cope with them.

This is the list of all environmental impacts of a ship that I could find through research on the internet: 1. Gas exhaust (SOx, NOx, CO2, CO, Particles, Hydrocarbons, Water, N2, O2, O3) 2. Garbage 3. Sewage (Grey-water, Black-water) 3. Bilge water 4. Spills and shedding (Load, Oil, Lubricants) 5. Anti-fouling coatings 6. Dismantling 7. Shipwrecks 8. Biodiversity (Ballast waters, Biofoils) 9. Sound 10. Swirls/waves 11. Dregging operations 12. Impacts/smashes (Animals, Plants)

Environmental ship index

Perhaps we can make an article called "Environmental Ship Index ? The idea is that there are port fee reductions given to ships that are comparitively less polluting. see http://www.environmentalshipindex.org/Public/Home KVDP (talk) 17:26, 13 May 2017 (UTC)

Should this article be specific to ships?

This article currently focuses exclusively on maritime transport. I just came to this page looking for a comparison between the environmental impact of the maritime portion of transportation vs other portions, especially last-mile delivery to consumers, and there's no information on this page. There's a small amount of what I want on Environmental impact of transportation, but it's pretty brief. To me, "shipping" can include all aspects of package delivery. --Dylan Thurston (talk) 20:58, 24 April 2019 (UTC)

Wastewater amount?

New new merge lists some estimates for wastewater for "one large ship" and "the cruise line industry" but some of these numbers have to be wrong, unless there is only one cruise ship in use at any time.Spitzak (talk) 22:35, 4 November 2022 (UTC)

Removed text block about Greenhouse Gas (GHG) Emissions Rating

I've removed this textblock as it was added a long time ago and no citation has been provided since Sept. 2022. Also, it's very detailed. Perhaps put parts of it back in with a suitable reference? +++++++

Another approach to reducing the impact of greenhouse gas emissions from shipping was launched by vetting agency RightShip, which developed an online "Greenhouse Gas (GHG) Emissions Rating" as a systematic way for the industry to compare a ship's CO₂ emissions with peer vessels of a similar size and type. Based on the IMO Energy Efficiency Design Index (EEDI) that applies to ships built from 2013, RightShip's GHG Rating can also be applied to vessels built prior to 2013, allowing for effective vessel comparison across the world's fleet. The GHG Rating utilises an A to G scale, where A represents the most efficient ships. It measures the theoretical amount of carbon dioxide emitted per tonne nautical mile travelled, based on the design characteristics of the ship at time of build such as cargo carrying capacity, engine power and fuel consumption. Higher rated ships can deliver significantly lower CO₂ emissions across the voyage length, which means they also use less fuel and are cheaper to run. EMsmile (talk) 12:52, 21 June 2023 (UTC)

New content to merge

Hi all. I rescued a draft from wp:AfC and moved it to User:Img22/Impacts of shipping emissions on health. Looks like there's some great content there if anyone wants to copy it into the article. Just remember to say "from User:Img22/Impacts of shipping emissions on health" somewhere in your edit summaries. Clayoquot (talk | contribs) 17:49, 14 February 2024 (UTC)
